All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

The following disclosure provides many different embodiments, or examples, for implementing different structures of the invention. In order to simplify the present disclosure, components and arrangements of specific examples are described below. They are, of course, merely examples and are not intended to limit the invention. Furthermore, the present invention may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed.

For ease of description, spatially relative terms, such as "inner," "outer," "lower," "upper," "above," "front," "rear," and the like, may be used herein to describe one element's or feature's relative positional relationship or movement to another element's or feature as illustrated in the figures. Such spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figure experiences a position flip or a change in attitude or a change in state of motion, then the indications of these directivities correspondingly change, for example: an element described as "under" or "beneath" another element or feature would then be oriented "over" or "above" the other element or feature. Accordingly, the example term "below … …" may include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative relationship descriptors used herein interpreted accordingly.

The embodiment of the application provides a cable joint 100, and the cable joint 100 is used for connecting two cables. It should be noted that the cable may be a power cable, a communication cable, a data cable, or the like, which is not limited to the present application.

As shown in fig. 1 and 2, the cable connector 100 includes a plug 10, a protection tube 20, and a locking connector 30. The plug 10 is connected with the external cable core 200 to realize functions such as signal transmission, power transmission or data transmission. Specifically, the plug 10 is internally provided with a connector 11, and one end of the external cable core 200 extends into the plug 10 and is connected to the connector 11.

It should be noted that the plug 10 is a part of the cable connector 100, and is typically located at one end of the cable. The external cable core 200 is the core of the cable responsible for transmitting electrical energy and information, and is generally composed of conductors and insulating materials to ensure the transmission quality of signals and the safe transmission of electricity.

It should be noted that the plug 10 may be a male connector or a female connector, which is not limited in the present application, and may be selected by those skilled in the art according to practical situations.

In addition, in order to protect the external cable core 200 from physical damage and external environmental interference, the protection tube 20 is wrapped around the outside of the external cable core 200. In particular, in the present embodiment, the protection tube 20 is made of a flexible material into a tubular structure, and has characteristics of wear resistance, pressure resistance, chemical resistance, and the like. Thereby, the external cable core 200 can be effectively protected from factors such as stretching, bending, extrusion, and external medium erosion.

In addition, in order to ensure firm connection between the plug 10 and the protection tube 20, the protection tube 20 is prevented from loosening or falling off in the use process, and the anti-loosening joint 30 is mounted in the plug 10 in a limiting manner and is connected with one end, close to the plug 10, of the protection tube 20.

It will be appreciated that when the protective tube 20 is subjected to an external force and a tendency is generated to move away from the plug 10, the check connector 30 moves away from the plug 10. At this time, since the locking joint 30 is limitedly installed in the plug 10, the locking joint 30 can be kept fixed under the limitation of the plug 10, thereby restricting the position of the protection tube 20 and preventing the protection tube 20 from falling off from the cable joint 100.

In summary, compared with the prior art, the cable joint 100 has at least the following advantages: the cable connector 100 is provided with the anti-loosening connector 30 connected with the protection tube 20 inside the plug 10, when the protection tube 20 is subjected to the action of external force and generates a movement trend in a direction away from the plug 10, the anti-loosening connector 30 can limit the position of the protection tube 20 so as to prevent the protection tube 20 from falling off from the cable connector 100, thereby reducing the risk of stress damage to the external cable core wire 200 and greatly prolonging the service life of the cable.

In order to better understand the solution of the present application by those skilled in the art, the following description will clearly and completely describe the solution of the embodiment of the present application with reference to fig. 1 to 2.

Further, as a specific implementation manner in some embodiments of the present application, as shown in fig. 1 and 2, a limiting structure (not shown) is disposed between the locking connector 30 and the plug 10, and the locking connector 30 is mounted inside the plug 10 by using the limiting structure in a limiting manner, so as to limit the movement of the locking connector 30 on the plug 10 and ensure the position fixing thereof. The spacing structure may take different forms, such as a mating design of protrusions and recesses, a threaded structure 40, or other suitable attachment means.

It should be noted that, by setting the limiting structure, the relative movement between the plug 10 and the locking connector 30 can be prevented, and further, the falling off of the protection tube 20 connected with the locking connector 30 is prevented, the reliability of the cable connector 100 under various working environments and vibration conditions is ensured, and the service life of the external cable is improved.

In an alternative embodiment, the limiting structure includes a first boss (not shown) and a second boss (not shown) adapted to the first boss, one of the check connector 30 and the plug 10 is provided with the first boss, and the other is provided with the second boss, and when the check connector 30 is mounted in the plug 10 in a limiting manner, the first boss abuts against the second boss.

In detail, the first boss is a protrusion or a raised structure, typically located on the surface of the check connector 30 or the plug 10. It may be a rounded, square or other shaped raised portion. Correspondingly, the second boss is a structure matched with the first boss and is positioned on the surface of the other part. The second boss is shaped and sized to match the first boss to ensure good mating of the two.

It will be appreciated that when the check connector 30 is mounted within the plug 10, the first and second bosses abut one another to form a secure connection. Meanwhile, when the protection tube 20 is subjected to an external force and generates a movement trend in a direction away from the plug 10, the protection tube 20 can limit its movement by an abutting action between the first boss and the second boss (i.e., a limiting action between the locking joint 30 and the plug 10), thereby preventing the protection tube 20 from falling off from the cable joint 100.

Preferably, in the present embodiment, the plug 10 is provided with the mounting groove 12, the groove wall of the mounting groove 12 is provided with the first boss, and the locking joint 30 is provided with the second boss at a corresponding position. Wherein the mounting groove 12 is a groove or channel in the plug 10, the shape and size of which are matched with the anti-loose joint 30, the anti-loose joint 30 is limitedly mounted in the mounting groove 12, so that the anti-loose joint can be firmly fixed in the plug 10.

The installation of the installation groove 12 enables the locking connector 30 to be accurately aligned with the plug 10, so that the plug 10 and the locking connector 30 can be correctly abutted, and dislocation or incomplete connection can be avoided.

Or in another alternative embodiment, the limiting structure comprises a limiting post (not shown) and a limiting hole (not shown) matched with the limiting post, one of the plug 10 and the locking joint 30 is provided with the limiting post, and the other is provided with a limiting groove, when the locking joint 30 is installed inside the plug 10 in a limiting way, the limiting post is inserted into the limiting groove.

Of course, in other embodiments, the locking connector 30 may be mounted in the plug 10 by using other limiting structures, which are not limited in the present application, and may be selected by those skilled in the art according to practical situations.

Further, as shown in fig. 1 and 2, in order to increase the connection strength and stability between the anti-loose joint 30 and the protection tube 20, in an alternative embodiment, a screw structure 40 is provided between the anti-loose joint 30 and the protection tube 20.

Specifically, a first screw thread (not shown) is provided on a part of the outer wall surface of the anti-loose joint 30, and a second screw thread (not shown) adapted to the first screw thread is provided on the inner wall surface of the protection tube 20. When the locking joint 30 is connected with the protection pipe 20, the portion of the locking joint 30 provided with the first thread is screwed into the protection pipe 20, and at this time, the first thread and the second thread are engaged with each other to form a tight connection.

As can be appreciated, by the screw structure 40 between the anti-loose joint 30 and the protection pipe 20, the connection strength and stability between the anti-loose joint 30 and the protection pipe 20 can be greatly enhanced, and the risk of the protection pipe 20 falling off can be reduced. In other words, the protection tube 20 of the cable connector 100 can be firmly fixed to the anti-loose fitting 30, providing reliable protection and fixing.

Or in another alternative embodiment, the cable joint 100 further includes a friction plate (not shown) disposed between the anti-loose joint 30 and the protective tube 20. Friction plates are typically made of a soft material, such as rubber or silicone, with good friction characteristics.

When the anti-loose joint 30 is connected with the protection pipe 20, a part of the anti-loose joint 30 is screwed into the protection pipe 20, and the friction plate is placed between the anti-loose joint 30 and the protection pipe 20 to play a role in filling and fastening.

It should be noted that, by providing the friction plate, the friction force between the anti-loose joint 30 and the protection tube 20 can be increased, so as to prevent the protection tube 20 from loosening or falling off during use. In other words, the friction plate can provide an additional fastening force, ensure a firm connection between the anti-loose joint 30 and the protection tube 20, and reduce movement between the protection tubes 20 under vibration or external force, reducing the risk of the protection tube 20 falling off from the cable joint 100.

Further, as shown in fig. 1 and 2, in order to prevent the external cable core 200 from being excessively bent, the cable joint 100 further includes a bellows 50, the bellows 50 is wrapped on the outer side of the protection tube 20, and one end of the bellows 50 is connected with the plug 10. The bellows 50 is a flexible pipe having a corrugated structure, and is typically made of metal or plastic.

It will be appreciated that when cable connector 100 requires bending, bellows 50 can withstand and distribute bending forces, reducing stress and damage to the internal cables, to provide bending protection to cable connector 100.

In addition, due to the flexible nature of the bellows 50, it is able to accommodate mounting environments of different angles and curvatures. This allows greater flexibility in the cable connector 100 to be installed and connected in complex wiring environments.

In addition, the bellows 50 can provide an additional protective layer against intrusion of dust, moisture, chemicals, etc. from the external environment into the cable joint 100. At the same time, the bellows 50 is also able to resist a degree of mechanical impact and compression, protecting the internal cables from damage.

Further, as a specific embodiment of the cable joint 100 provided by the present application, as shown in fig. 1 and 2, in order to facilitate the penetration and connection of the core wire, the locking joint 30 is provided with a through hole 31 for the core wire to pass through.

As will be appreciated, the through hole 31 refers to a hole or passage provided in the anti-loose fitting 30 for passing through the core wire. By providing the through hole 31, the core wire can pass through from one side of the locking joint 30 and then be connected with the connector 11 inside the joint. In this way, the check connector 30 can not only provide the fixing and check functions of the protection tube 20, but also allow the core wire to be introduced into the cable connector 100 from the outside and connected to the internal circuit.

It should be noted that the design of the through holes 31 will generally take into account the size and number of core wires to ensure that the through holes 31 are sized and shaped to accommodate the desired core wires. The through holes 31 may have different shapes, such as circular, oval or rectangular, to accommodate different types and sizes of core wires. The present application is not limited thereto, and those skilled in the art can select according to actual circumstances.

Based on the cable connector 100 described above, the embodiment of the present application further provides a cable, where the cable includes the cable connector 100 described above.
